怎么能把正在验证放到输入框后面显示

为表单添加.form-horizontal类
将label和控件包裹在.control-group中
提示信息用<span>放在input的后面，示例代码如下：
<form class="form-horizontal">
<div class="control-group">
<label class="control-label" for="inputEmail">Email</label>
<div class="controls">
<input type="text" id="inputEmail" placeholder="Email">
<span class="help-inline">Something may have gone wrong</span>
</div>
</div>
</form>

好！
